Another exciting first in my motorcycling career last night: riding home in a tow truck! I've only had the bike a couple of days, so I'm thrilled to be getting off on the right foot. The ride home from buying the bike on tuesday was 30 mins. Enough to fully charge the battery, right? Last night, thursday, I took it out to a carpark for practice, but the carpark was shut. So I pulled over, turned off the key and checked my map for carpark B. When I tried to fire it up, it wouldn't turn over until I turned the high beams off. "Kinda lame," I thought and proceeded to carpark B. Carpark B was full of cars, so I pulled over and keyed off again. Then it wouldn't start at all. The instrument lights visibly dimmed between one attempt and the next. Later, after my exciting tow truck ride, I connected the bike to my car battery and it soon started and ran just fine for 30-60 seconds – but the engine cut out as soon as I disconnected the car. I did this twice with the same result. Haven't had a chance yet to multimeter anything. So my diagnosis is that the battery is ok, but not charging, so it's probably a wrecked regulator-rectifier that need to be rectified. Can I get a second opinion please?
